Yeah, just realised I forgot that, too.
** Description changed:
+ [Impact]
+ Tomcat won't start, unless default-jre-headless or openjdk-8-jre-headless is
installed.
+
+ If openjdk-11-jre is installed, it won't be used, unless default-jre-
+ headless is installed.
+
+ [Test Case]
+ In a minimal install:
+
+ # apt install tomcat8 openjdk-11-jre-headless
+ # service tomcat8 start
+
+ If you get this error, you have reproduced the bug:
+ * no JDK or JRE found - please set JAVA_HOME
+
+ If it starts, all is good
+
+ [Regression Potential]
+ For some users, tomcat may now use Java 11 where it was previously using Java
8.
+
+ [Bug Description]
The tomcat8 init script contains:
find_jdks()
{
- for java_version in 9 8
- do
- for jvmdir in /usr/lib/jvm/java-${java_version}-openjdk-* \
- /usr/lib/jvm/jdk-${java_version}-oracle-* \
- /usr/lib/jvm/jre-${java_version}-oracle-* \
- /usr/lib/jvm/java-${java_version}-oracle
- do
- if [ -d "${jvmdir}" ]
- then
- JDK_DIRS="${JDK_DIRS} ${jvmdir}"
- fi
- done
- done
+ for java_version in 9 8
+ do
+ for jvmdir in /usr/lib/jvm/java-${java_version}-openjdk-* \
+ /usr/lib/jvm/jdk-${java_version}-oracle-* \
+ /usr/lib/jvm/jre-${java_version}-oracle-* \
+ /usr/lib/jvm/java-${java_version}-oracle
+ do
+ if [ -d "${jvmdir}" ]
+ then
+ JDK_DIRS="${JDK_DIRS} ${jvmdir}"
+ fi
+ done
+ done
}
# The first existing directory is used for JAVA_HOME (if JAVA_HOME is not
# defined in $DEFAULT)
JDK_DIRS="/usr/lib/jvm/default-java"
find_jdks
When the default-jre package is installed, this detects Java 11, but
when it isn't, it doesn't.
# apt install tomcat8 openjdk-11-jre-headless
# /etc/init.d/tomcat8 start
- * no JDK or JRE found - please set JAVA_HOME
+ * no JDK or JRE found - please set JAVA_HOME
This was fixed in Debian in 8.5.31-1
